BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘INCALDOBLU’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa. The objective of the breeding program is to create new mounding and early-flowering Calibrachoa plants with attractive double flowers and good garden performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in November, 2015 of Calibrachoa Llave & Lex. ‘KLECA09208’, disclosed in U.S. Plant Pat. No. 22,600, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number Ca14-5446-2, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and first selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Johannesburg, South Africa in April, 2017.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Gensingen, Germany since April, 2017 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘INCALDOBLU’. These characteristics in combination distinguish ‘INCALDOBLU’ as a new and distinct Calibrachoa plant:

-   -   1. Uniformly low mounding to outwardly spreading to eventually         trailing plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit; dense and bushy appearance.     -   4. Early and freely flowering habit.     -   5. Large double flowers that are purple to light purple in         color.     -   6. Good garden performance.

The new Calibrachoa plant can be compared to plants of the female parent, ‘KLECA09208’. Plants of the new Calibrachoa differ primarily from plants of ‘KLECA09208’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more freely branching and         denser than and not as open as plants of ‘KLECA09208’.     -   2. Plants of the new Calibrachoa flower earlier than plants of         ‘KLECA09208’.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more outwardly spreading         than and not as upright as plants of the male parent selection.     -   2. Plants of the new Calibrachoa are more freely branching than         plants of the male parent selection.     -   3. Plants of the new Calibrachoa have double flowers whereas         plants of the male parent selection have single flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘KLECA15269’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘KLECA15269’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more freely flowering than         plants of ‘KLECA15269’.     -   2. Plants of the new Calibrachoa have larger flowers than plants         of ‘KLECA15269’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant.

At the top of the photographic sheet is a side perspective view of a typical flowering plant of ‘INCALDOBLU’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘INCALDOBLU’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
